The Apple Watch Sport Loop band was woven from nylon thread to create a hook-and-loop closure. These bands were available for the 40 mm and 44 mm Apple Watch models, and were offered in sizes to fit 130–200 mm wrists (40 mm) and 145–220 mm wrists (44 mm). The bands also fit older Apple Watch sizes.
This Alaskan Blue band used two main colors including slate blue and dark blue. Contrasting cream-colored stripes flanked both sides of the band. The connector and closure plastics were slate blue. Uncharacteristically, the inside hooks (that cannot be seen while wearing the band) were bright orange.
Apple described the Apple Watch Sport Loop band:
“Soft, breathable, and lightweight, the Sport Loop features a hook-and-loop fastener for quick and easy adjustment. The double-layer nylon weave has dense loops on the skin side that provide soft cushioning while allowing moisture to escape. On the reverse side, the attachment loops are securely anchored for superior durability.”
